machines, the program runs in a separate 64K bank, and zeropage variables need
to be copied from the system bank into the execution bank to read by a simple
load operation. The change is currently untested!

named EXEHDR.
* Renamed BASICHDR to EXEHDR for the PET-II machines.
* Moved the call to CHRCH in front of the code that saves the zero page, since
open files are sometimes remembered in the zero page, so we need to close
them before we grab a copy.

main() is encountered. Define this symbol in the startup code. This will
automatically force linking of the startup code which can then reside inside
the standard library as any other object file.

before calling initlib because initlib calls contructors and may install
drivers, which enable hardware interrupts. Similar for donelib.
See also R3897 and R3951 where this change was done for other platforms.

in the system bank. For one this performs better (several %), second it
allows to handle the function keys in conformance with other platforms.
Without the custom keyboard routine, we would have to apply some more
magic to the function keys to make them work as with other cc65 targets.

Use wrappers to call the kernal in bank 15 instead of implementing kernal
functionality within the cc65 libs (eats performance but is much smaller and
simpler).
Improved startup/shutdown code allows a return to the system bank without
calling the BASIC cold start vector.

to emulate these functions on platforms where one or more of these functions
are not available (PET, CBM-II).

separate module that contains a module constructor. In some cases, the
code was even unnecessary, since the screen size is known in advance.
